2. TOPICS:
•Introduction
•Virtual keyboard technology
•Different virtual keyboards
•Applications
•Advantages
•Drawbacks

3. INTRODUCTION
•Touch Typing Device
•Compact And Faster
•Use sensor technology and AI
•Use infrared cameras to interact
•Finger tracking based Interface
•VKB has no physical support
•Works on any surface
•Used when our normal keyboard fails

4. VIRTUAL KEYBOARD TECHNOLOGY
The System Comprises Of Three Module:
•The Sensor Module
•IR Light Source
•The Pattern projector

6. TYPES OF VIRTUAL KEYBOARD
•VKB PROJECTION
•SENSE BOARD
•SCURRY
•V TYPE

7. VKB PROJECTION
A projection keyboard is a form of computer input device whereby the image of a virtual keyboard is projected onto a
surface: when a user touches the surface covered by an image of a key, the device records the corresponding keystroke.

8. SENSE BOARD
Consists of two rubber pads that
slips onto user’s hand
Muscle movements in the palm
are sensed
Translates movements into key
strokes by pattern recognition

9. SCURRY
Next generation glove like,
wearable device
Allows user to punch in letters
without a keyboard
Operates computer by moving
two hands in empty air

10. V TYPE
Detects key strokes in air with a
given glove
Active finger tracking method is
used

11. APPLICATIONS
•In Operation Theaters
•In high tech and Industrial sectors
•Used with smart phones and PDA’s
•In word processing, email and spread sheet tasks
•As compute PDA input
•Gaming control
•TV remote control

12. ADVANTAGES
•Laser can be projected on any surface or even in the air
•Used where low noise is essential
•Typing does not requires a lot of force
•Touch typing paradigm can be adjusted
•Plug and play device
•No driver software necessary
•High battery life

13. DRAWBACKS
•VKB is hard to get used to
•Typing in thin air requires a little practice
•Projected keyboard should not be used in bright room
•The devices are very costly

14. CONCLUSION
•Provides the convenience of compactness with the advantages of a
QWERTY keyboard
•Based on a true-3D optical range camera
•Used in 6th Sense Technology Device which does not depends on
surface
•Thus virtual keyboards will make typing easier, faster, and almost a
pleasure
